LPub3D is an Open Source WYSIWYG editing application for creating LEGO® style digital building instructions.

LPub3D output include instruction document, document pages, part list and export content.

PNG PNG-Logo Portable Network Graphics images, instruction document pages and POV-Ray rendered images
JPEG JPG-Logo Joint Photographic Experts Group instruction document pages
BMP BMP-Logo Bitmap instruction document pages
HTML HTM-Logo Hypertext Markup Language sortable graphic part list with element ID and online part lookup
BrickLink XML XML-Logo Extensible Markup Language BrickLink part list
CSV CSV-Logo Comma-Separated Values plain text part list
POV POV-Logo Persistence of Vision Ray Tracer (POV-Ray) photo-realistic scene files
OBJ OBJ-Logo Wavefront Object files
STL STL-Logo Stereolithography object files
3DS 3DS-Logo Autodesk 3DStudio Max object files
DAE DAE-Logo COLLAborative Design Activity object files

LPub3D uses the LDraw standard and LEGO® Geometrical Equivalent Objects (LGEO) photo-realistic part libraries and reads the LDraw DAT, LDR and MPD model file formats. The LDraw libraries are not required to be preinstalled. Archive (.zip) library files for both official and unofficial LDraw parts are bundled with LPub3D. Follow the linked image below to acquire the LGEO photo-realistic part library.

LDraw LDraw-Logo LDraw™ parts is an open standard library that allow users to create virtual models and scenes. Three LDraw part libraries are bundled with LPub3D.
LEGO LDraw™ official and unofficial LEGO® part library.
TENTE TENTE® unofficial LDraw part library created by José Alfonso Solera (Jasolo).
VEXIQ VEX IQ® unofficial LDraw library created by Philippe Hurbain (Philo).
LSynth LSynth bendable parts synthesis elements created by Kevin Clague and updated by Don Heyse (deeice).
LGEO LGEO-Logo POV-Ray photo-realistic part library created by Lutz Uhlmann (El Lutzo), updated by Owen Burgoyne (C3POwen) and extended with STL object files by Damien Roux (Darats).

LPub3D Blender integration uses the LPub3D Blender LDraw Addon which imports LDraw™ models into Blender, exports models from Blender and renders imported models using the full range of Blender capabilities. LPub3D also provides “native” 3DViewer, POV scene file generation, including POV-Ray PNG image rendering using integrated modules based on LeoCAD and LDView. Additionally, LDView, LDGLite and POV-Ray 3rd-party stand-alone LDraw model renderers are bundled in each LPub3D distribution. All stand-alone renderers are console applications custom adapted to LPub3D for tight integration, optimum configurability and robust performance.

LeoCAD LeoCAD-logo LPub3D “native” renderer and 3D Viewer - performant, “true fade” rendering
Blender Blender-Logo Best in class, 3D computer graphics toolset for high quality photo-realistic renderings
LDGLite LDGLite-Logo fast image rendering ideal for proofing
LDView LDView-Logo high quality rendering plus POV scene file generation
POV-Ray POVRay-Logo ray tracing renderer - photo-realistic, feature rich rendering
